HAIR-CUTTING INSTRUMENT.

Specification of Letters Patent.

Patented Mar. 1 1, 1916.

Application filed October 18,1915; Serial'NdSBAZO.

To all whom it may concern Be it known that LGEoRon A. SzABo, citi zen of the United States, residing at Cleve; land, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Hair-Cutting Instruments, of which the following is a specification.

My invention relates to a hair cutting instrument, comprising the construction and arrangement of parts substantially as hereinafter' shown and described and more particularly pointed out in the claims.

The object of the invention is to provide a simple form of cutting tool adapted to be held in one hand and passed through the hair like a comb and to be operated during a combing movement to cut the hair, the cutting device having means to adjust the'degree of cutting movement thereof to permit cutting of the hair to any desired length.

In the accompanying drawings, Figure 1C is a plan view and Fig. 2- is a side elevation of the instrument. Fig. 3 is a sectional view and side elevation, showing the cutting blade depressed. Fig. 4 is a cross section of the handle, enlarged, on line M, Fig. 3. Fig. 5 is a side view, partly in section of the head portion of the instrument, with the front plate and cutting blade removed. Fig. 6, is an end view of the head portion of the instrument showing the removable face plate in place therein. Fig. 7 is a sectional view' in plan and enlarged, on a line horizontally through the operating levers.- Fig. 8 is a cross section on line 8-8, Fig. 7. Fig. 9 is a perspective view of the divisionv wall and comb, and Fig. 10- a perspective view of the cutting blade. Figs. 11, 12 and 13 are end, side and sectional'views, respectively, of a clamping holder adapted to be used in stropping the cutting blade.

The instrument comprises a sectional body, stamped or molded of aluminum or sheet metal to provide a recessed head 2 and a two piece hollow handle 3 projected forwardly at an angle to said head. The front side of head 2 is open and bordered top and bottom by channels adapted to hold a removable face plate 5 slidably in place, said plate having a finger catch 6 .to facilitate withdrawal thereof from the end of the head. The bottom portion of the head is tapered or beveled on rounded or straight lines on oppositesides thereof and also slotted transversely at close intervals to provide a toothed comb 8 consisting of two similar rows ofteeth which are joined together at I their bottom edges but separated above that point to accommodate operation of a; cutting blade 9 vertically therebetween. This blade is held in close working engagement .with a backing plate 10 removably stationed as a central division wall in the head 2. The upper and front end edges of the plate have projecting lips 11 adapted to rest in corresponding notches'12 in the top and front end flanges of the head, and'the bottom edge portion of the plate is beveled and adapted'to rest upon a shouldered seat 13 within the comb portion of the head and being also formed with a row of teeth 14 corresponding to the comb teeth of said'head. Two curved slots 15 in backing plate 10,'and-two straight edge slots 16 in blade 9 accommodate two round lugs or pins 17 and 18 extending forwardly from the free working ends of two operating levers l9 and 20,. respectively, which are pivotallyand loosely connected approximately at a centralpoint with each other by a short trunnion 21 andv supported to swing from the rear wall "of the head and from division or backingplate 10 by short pins 22 and 23, see Fig. 7 Lever 20 is provided with a widened extension 24 which projects and is free to move up and down within the hollowv handle 2, and a thumb screw 25 engaged with said extension pro jects through an opening'in the top of said handle and. is adapted to be pressed by the finger or thumb of the holding hand of the operator. .The bottom end of thumb-screw 25 engages a stop lug 26 within the bottom of the handle and adjustment ofthe thumbscrew determinesthe degree of downward 'movement adapted to be imparted to the operating levers and thecutting blade 9. The upward or return movements of the blade and its operating parts is brought about by a spring 27, secured between the two halves of the handle .3, seeFig. 3. In this way, a reciprocal movement in a greater or less degree is imparted to blade 9 by a finger or thumb movement during combing of the hair,'or movement of the instrument step by step through the hair, to cut the hair to any desired length.

in Figs. 11 to 13 I show a cylindrical holder 28 to permit stropping of the cutting blade, said holder having a slot 29 to admit the blade, and being provided with a beveled bolt 30 and aitightening screw 31 to wedge the blade, removably within the slot at a tangent to the axis of the holder.

What I claim is:

1. A hair cutting instrument, comprising a hollow comb, a division wall within said comb, a movable cutting blade adjacent said wall,'and operating members for said blade extending through said wall having means projecting through said comb adapted to befor said blades pivotally engaged with each other and the ends of said blade and ally mounted upon said comb.

4. A hair cutting instrument, comprising a hollow comb having a cutting blade and a backing member for said blade removably mounted therein, and a pair of pivoted levers supported by said comb and engaged with the opposite ends of said blade and a finger-engaging extension and a spring to operate said levers and blade.

5 A, hair cutting instrument, comprising a hollow comb made in separable sections having a removable division wall therein, a cutting blade at one side of said wall and operating mechanism for said blade at the other side of said wall.

6. A hair cutting instrument, comprising a hollow head and handle made in separable pivotsections and provided with a toothed comb portion, a cutting blade in co-acting position with said comb portlon, a backing plate for said blade, operating levers for said blade mounted adjacent said plate, a finger-engaging member to actuate said levers and blade and a spring within the handle engaged with said extension.

7. A haircutting instrument comprising avhollow comb having a cutting blade and operating mechanism for the blade mounted within said comb, and an adjustable screw to limitthe movement of said blade and operating mechanism.

8. A hair cutting instrument having a hollow body with a handle and a comb portion at the bottom thereof, a cutting blade in coacting relations with said comb portion, and operatingmechanism for said blade having a depressible part in the base of said handle and means therewith to depress said blade uniformly at both ends.

9. A hair cutting instrument, comprising 7 a hollow comb having a handle, a cutting blade and a backing, plate therefor confined within said comb, and a depressible operating member for said blade extending outside said comb at the base of said handle and adapted to be actuated by a finger of the hand holding the said handle.

10. A hair cutting instrument, comprising a hollow comb and a-removable face plate at the front side thereof, in combination with a cutting blade removably' confined behind said plate, and means to depress and to raise said blade alternately within said comb. 11. A hair cutting instrument comprising a hollow body with a comb at its bottom and a handleat one end, a removable plate on thefront of said body and'a cutting blade and backing plate and operating members for said blade, removably mounted within said comb behind said face plate and one behind the other successively.

12. A hair: cutting instrument comprising a hollow comb having a handle projected forwardly at an angle thereto, a cutting blade within said comb and actuating means for said blade comprising a depressible operating member exposed at the base of said handle. e

In testimony whereof I aflix my signature in presence of two witnesses.
